Description

Technical Field

[0001] The utility model relates to a device for detecting the weight consistency of a battery plate, belonging to the technical field of storage batteries. Background Art

[0002] The plate is one of the core components of the lead-acid battery. It is made of lead paste applied to the grid-shaped grid. The quality of the plate manufacturing will be directly related to the performance of the battery. Therefore, the quality requirements for the plate manufacturing process are very strict, especially the control of the plate weight. In order to maintain the stability and consistency of the plate weight, a large number of plates need to be extracted during the manufacturing process for weight detection. In order to facilitate processing and maintain high production efficiency, the current automotive lead-acid battery cast plate is basically designed to connect two small plates into a large plate that is symmetrical on the left and right for manufacturing, and then cut and used to assemble the battery. In order to maintain the consistency of the amount of paste applied to the two connected plates on a large plate during the manufacturing process, the currently commonly used detection method is: extract a large plate at regular intervals during the manufacturing process, cut the two small plates apart with scissors, and then use an electronic scale to measure the weight of the two small plates respectively. The consistency of the plate weight is determined based on the weight deviation of the two small plates, and then determine whether to adjust the equipment process parameters to make the weight of the two small plates consistent. The existing plate weight consistency detection method has the following main disadvantages: 1. When weighing, it is necessary to cut the two connected plates apart, which is cumbersome to operate, increases labor intensity, and affects production efficiency; 2. After the two connected plates are cut apart, they cannot be used in subsequent production and can only be treated as waste. The number of random inspections during manufacturing is large, resulting in great waste. Utility Model Content

The vertical baffle 2-2 is vertically connected to the horizontal support plate 2-1. The side support plates 2-3 are provided with two, which are isosceles triangles, which are vertically fixed on the left and right ends of the horizontal support plate 2-1, and are respectively connected to the two ends of the vertical baffle 2-2, so that the vertical baffle is more stable and avoids the vertical baffle from being tilted under force. There are two plate limit blocks 2-4, which are symmetrically arranged on the horizontal support plate 2-1 with the center line of the horizontal support plate as the axis of symmetry.

[0019] The pole plate limit block is set as a position-adjustable structure, which is adjusted by adjusting the screw rod 2-5.

[0021] Combination Figures 1 to 3 Explanation of the weighing process: During the weighing process, it is necessary to ensure that the two connected plates, the weighing platform and the electronic scale are symmetrically arranged with the center line of the horizontal support plate as the axis. The specific installation weighing process is:

[0022] a. Place two electronic scales 1 side by side on a horizontal workbench, and then place the weighing platform 2 on the two electronic scales. The bottoms of the height adjustment screws 2-7 at both ends of the weighing platform are supported and placed on the surfaces of the two electronic scales. Adjust the distance between the two electronic scales so that the height adjustment screws 2-7 set at the left and right ends of the horizontal support plate 2-1 are placed on the center lines of the two electronic scales;

[0023] b. According to the width W1 of the two connected plates to be weighed, the adjusting screw 2-5 on the horizontal support plate is adjusted, thereby synchronously and reversely adjusting the spacing of the two plate limit blocks 2-4 on the weighing platform, keeping the root spacing W of the two plate limit blocks consistent with the width W1 of the plate, that is, W=W1, and keeping the two plate limit blocks symmetrically distributed along the center line of the vertical baffle, that is, W2=W3;

[0024] c. Adjust the weighing platform to a horizontal level;

[0025] d. Turn on the two electronic scales and set the displayed data to "zero". The plate weighing is ready.

[0026] e. Place the two connected plates on the weighing table, with the bottom edge of the plate placed in the slide groove on the horizontal support plate and stuck between the two plate limit blocks, and the side of the plate naturally resting on the vertical baffle;

[0027] f. Read the weighing values ​​G1 and G2 of two electronic scales. The sum of G1 and G2 is the actual weight G of the two connected plates, that is, G = G1 + G2. The difference between G1 and G2 is the weight difference δ between the two small plates, that is, δ = |G1-G2|;

[0028] g, the weight G of the two connected plates and the weight difference δ of the two small plates obtained by weighing, the total weight G of the two connected plates with the same technical requirements 总 ±δ1 and the weight difference δ2 between the two small plates are compared, and the weighed G is located at G 总 When the weight of the two connected plates is within the range of ±δ1 and δ is less than δ2, it is determined that the weight of the two connected plates meets the technical requirements, otherwise it does not meet the technical requirements;

[0029] h. Decide whether to adjust the plate coating weight based on the weighing and judgment results.

[0030] Taking the 115 (10) positive electrode plate coating as an example, the detection device of the present invention is used to weigh and measure the two small plates on the left and right of a large plate at the same time (the weighing steps are as above). The parameter requirements of the 115 (10) positive electrode plate coating are as follows Table 1:

[0031] Table 1 115(10) positive plate coating parameters

[0032]

[0033] During the coating process of 115 (10) positive plates, the weight of a large plate is randomly measured every 15 minutes, and the amount of plate paste is adjusted in time according to the compliance of the plate weight. The randomly measured plates are first weighed by the detection device of the present invention, and then the weight of a large plate and the weight of the two small plates after cutting are weighed by the existing method (i.e., the weight of a large plate is first weighed, and then the two connected plates are cut into two small plates, and the weight of the small plates is weighed respectively). The results are compared in Table 2.

[0034] Table 2 Sampling results

[0035]

[0036] Note: The weight of the large piece in this measurement method is the sum of the weights of the left and right small pieces.

[0037] From the comparison results of the spot check weight in Table 2, it can be seen that the weight of the left and right small plates and their sum measured by the detection device of the present invention are very different from the weight of the left and right small plates and the weight of a large plate measured by the existing detection method, which is basically within 0.2g, and meets the measurement accuracy requirements of the measurement device of the present invention. In addition, the detection device of the present invention can accurately and quickly obtain the qualified status of the plate coating, avoiding the waste of the plate.
